How to Root Google Pixel Android O Developer Preview 1

Google is always trying to keep its phones updated to the latest version of Android. Recently, Google released Android 7.1.2 Nougat for the Pixel smartphones. Google also released the new Android 8 named as Android O in the developer preview form. The developer preview is meant to give the users a glimpse of what the new OS is going to look like. It doesn’t contain complete features of the upcoming operating system, it has most of the features missing in the preview form. The developer view of Android O can be installed only on a few devices, it doesn’t even run on older Google Nexus devices. Luckily, it can be installed on both the Google Pixel and Google Pixel XL.

Google Pixel and Pixel XL are the pure beasts if you wish to customize them and unleash their potential. Without root, these phones may seem incomplete to many. It was quite hard to root these phones running Android O Developer Preview 1. A method came up earlier, but that rooted the Nexus 5X and Nexus 6P only. The Google Pixel and Pixel XL were not rooted so far.

XDA member Sachi315 discovered a method to root both the Pixel and Pixel XL running Android O. The method runs Android 7.1.2 Nougat on one slot and runs the Android O in the other slot. It makes the use of both these OS to achieve root on the O. In order to make it happen, users need to download the 7.1.2 images and modify them, they need to add a few lines of codes to the flash files, and then flash those files on the phone leading towards the root access.

Here in this post, I have tried, to sum up, the entire method in a few easy steps. You can follow the steps now to Root Google Pixel Android O Developer Preview 1.
